Below is a (non-exhaustive) list of projects that I do in my free time. This
being a limited resource (free time, I mean), the maturity of the projects
tends to vary. I’m always happy to receive pull requests if your business
decides to use one of them, though.

Licensing information should be available for most of them. I choose my licenses
based roughly on the following guidelines:

small helpers usually get MIT or even
CC0, such
that somebody in need can quickly cut and paste without worrying to much about
the legal department’s opinions

real projects tend to get GPLv3,
because I believe in software freedom (thanks, RMS)

modifying stuff that I did not write is obviously subject to other peoples’
licensing models

some projects might demand a specific license when linked, I’ll naturally
comply with that

Note that if there is no license information available, the project is
by defaultall rights reserved (this is just an observation, not a declaration).

Current Projects

Here are the projects where I invested (at least a little) time in the past
months.

Postfix Address Mapping Service

I wrote an implementation of the postfix
tcp_table protocol both
in Python and in OCaml. The former implementation was just a quick hack to
enable address normalization on my mail server, the latter was a toy project
for learning OCaml, but I’d consider it the superior one now.

Setup Helpers

Setting up virtual machines is tedious? It shouldn’t be! See my collection of
helper scripts to setup ubuntu machines for kubernetes. Note that the choice
of packages is strongly dependent on my preferences - but you can probably learn
a lot about me if from the apt-get commands and *rc files.
